In a preferred solution, a retractable mechanism, such as a steel rope having a winching structure, is arranged on the connecting rod 211. This structure enables the four bar linkage 212 and inner yarn winding package 48 in their entirety to descend, so as to directly be put into the spindle bucket 18. Preferably, the rotary swaying arm 27 is arranged above the spindle bucket 18, and a twister is arranged on the rotary swaying arm 27, so as to dodge the inner yarn winding package 48 by swaying, thereby avoiding hindrance to donning operation.

As a preferred solution shown in FIGS. 4-6, the sliding rail 34 is arranged on the machine frame 10, the sliding frame 35 is slidingly connected with the sliding rail 4, the spindle bucket 18 and the twisting mechanism 26 are arranged on the sliding frame 35, and the sliding frame 35 is configured to slide out from or into one side of the twisting machine 8. This structure enables sharp reduction of the labor intensity for donning the inner yarn winding package 48. A single winding package for some yarn to be twisted weighs more than 10 kg, so it needs very high labor intensity to don yarn massively by manpower. Adopting the structure capable of pulling out the spindle bucket 18 enables the inner yarn winding package 48 to be directly put in it.

Preferably, the articulating connection rod 452 has its one end provided with the ball head 456 and its other end provided with the opening groove 457; when two inner yarn carrier assemblies are connected with each other, the ball head 456 is positioned inside the opening groove 457, so that a pull or push force can pass through them. When the inner yarn branch rail-lifting section 131 ascends or descends in its entirety, the ball head 456 can be easily disconnected from or reconnected with the opening groove 457.

In another optional solution, the inner yarn carrier assemblies are connected with each other by the articulating connection rod 452 into an entirety, thus its length corresponds to the length of the twisting machine 8, and the length of the twisting machine 8 also corresponds to the length of the inner yarn branch rail-lifting section 131.

Example 2

As shown in FIGS. 1-13, the outer yarn winding package 47 and the inner yarn winding package 48 are conveyed to the original yarn delivery area 4 by the carrier 402, and then loaded on the outer yarn carrier assembly 25 and the inner yarn carrier assembly in the outer yarn preparation area 1 and the inner yarn preparation area 2, respectively; the articulating connection rod 452 of the outer yarn carrier assembly 25 preferably adopts the pinned articulating connection structure shown in FIG. 9, and the articulating connection rod 452 of the inner yarn carrier assembly preferably adopts the ball head connection structure shown in FIG. 11, and the inner yarn carrier assembly includes the inner yarn hugging suspending device 45 and the inner yarn suspending device 21. The outer yarn carrier assembly 25 and the inner yarn carrier assembly pass through the in-air conveying rail 3, then are conveyed to the outer yarn branch rail 12 and the inner yarn branch rail 13 via the diverging-and-merging switch 6, respectively; the means for conveying and driving may be the travel driving unit 22, which includes an electric motor and a friction wheel, and the friction wheel touches the articulating connection rod 452, and drives it to move.

The outer yarn carrier assemblies 25 are conveyed by group to the position of the twisting machine 8 in the twisting area 5, and form the carriage 11 by temporary fixation. The outer yarn guiding rail 101 is arranged on the machine frame 10, and the outer yarn guiding wheel 464 is arranged on the outer yarn seat 462 in the outer yarn carrier assembly 25, for example, in the outer yarn seated suspending carrier assembly 46; when the outer yarn seated suspending carrier assembly 46 moves to the position of the twisting machine 8, the outer yarn guiding wheel 464 enters the outer yarn guiding rail 101, and holds up the outer yarn seat 462 of the outer yarn seated suspending carrier assembly 46 to keep it in an incline state, for inconvenience to twisting operation. During operation, operators complete connecting yarn on the ascending trolley 17, without necessity to move the outer yarn winding package 47; after finishing twisting operation, operators remove the small-diameter outer yarn winding package 16 and places it on the tube seat 15 of the fixed frame 9, and the bobbin used up on the fixed frame 9 is placed on the shelving plate 14. The travel driving unit 22 conveys the current outer yarn carrier assembly 25 away, then the next outer yarn carrier assembly 25 carrying the outer yarn winding package 47 comes on. The footstep 172 is arranged on the ascending trolley 17, the bottom of which is provided with the ground wheel 171, one side of the bottom of the twisting machine 8 is provided with the ascending trolley guiding rail 19, and the guide pulley mechanism 20 is arranged on the ascending trolley 17, and slidingly connected with the ascending trolley guiding rail 19, so that the ascending trolley 17 can run along the twisting machine 8. A plurality of the inner yarn carrier assemblies of the inner yarn suspending device 21 taken as an example are conveyed to the position of twisting machine 8, the inner yarn branch rail-lifting section 131 descends in its entirety. For a winching lifting device taken as an example in FIG. 8, as the lifter driving motor 40 acts to drive the lifting main shaft 41 to rotate by a gear set, such as a bevel gear set, the winching wheel 42 on the lifting main shaft 41 rotates, so as to release the winching belt 43 from the winching wheel 42, so that the lifting rail 38 of the inner yarn branch rail-lifting section 131 slides along the lifter guiding wheel 39, achieving entire descent. In the inner yarn carrier assemblies positioned at the both sides of the inner yarn branch rail-lifting section 131, such as, the articulating connection rod 452 of the inner yarn suspending device 21, the ball head 456 departs from the opening groove 457; or the length of the entire section of the inner yarn suspending device 21 is equal to that of the inner yarn branch rail-lifting section 131, at descending, the inner yarn suspending device 21 with its entire section descends.

Moreover, as shown in FIGS. 4-6, the driving device 33 drives the sliding main shaft 31 to rotate by the transmission mechanism 32, the sliding main shaft 31 brings the sliding gear 30 to rotation, the sliding gear 30 brings the sliding rack 29 to action, the sliding rack 29 is fixed on the sliding frame 35, so that the sliding frame 35 brings the spindle bucket 18 and the twisting mechanism 26 to sliding movement out from the twisting machine 8, and the twisting mechanism 26 includes an electric spindling assembly.

Either of the structure of the sliding frame 35 and the structure of the rotating swing arm 27 is selectable, that is, one of both can be used; the structure of the sliding frame 35 brings about low labor intensity, but costs increase more for the twisting machine 8. The driving device 33 acts again, so that the sliding frame 35 slides back to the twisting machine 8, and the forementioned steps enables the twisting machine to complete automatic donning. After completing donning, the lifter driving motor 40 acts, so that the inner yarn branch rail-lifting section 131 ascends in its entirety. In the inner yarn carrier assemblies positioned at the both sides of the inner yarn branch rail-lifting section 131, such as, the articulating connection rod 452 of the inner yarn suspending device 21, the ball head 456 is connected with the opening groove 457 again. The travel driving unit 22 acts again, then conveys the inner yarn carrier assembly carrying a new inner yarn winding package 48 to the position of the twisting machine 8.
